Logging
|
|
=======
|
|
|
|
Logging subscribers emit debug-level messages for store, retrieve, lookup,
|
|
L1, and StorageManager events via Python's standard ``logging`` module.
|
|
|
|
When OpenTelemetry is installed, ``init_logger`` automatically attaches an
|
|
OTel ``LoggingHandler`` so that log records are forwarded to any configured
|
|
OTel ``LoggerProvider``. The handler respects the ``LMCACHE_LOG_LEVEL``
|
|
environment variable.
|
|
|
|
.. code-block:: bash
|
|
|
|
LMCACHE_LOG_LEVEL=DEBUG lmcache server ...
|
|
|

Key log messages:
